At least me, I use flash cards. I write the character many times to memorize it too.
Make sure you know the difference between Onyomi and Kunyomi readings, but at the same time, I’d focus more on learning words with the character.
For example, let’s say you can learn four words from the kanji “題”, and also learn sentences that use the words so you can familiarize yourself with the usage.
That way, you get to know vocabulary, grammar, and kanji all at once to help you become more fluent.
